Different chemicals work better under different conditions: for example, under high flow conditions, pebble quicklime and hydrated lime are the most cost effective. Furthermore, AMD from each mine is unique due to the different combinations of acids and metals, and needs to be analyzed so the chosen chemicals are the best tailored to neutralize the specific acids and metals present [23].

For example, a soil with a pH of 5.5 is ten times more ,acid, than a soil with a pH 6.5, and a soil with pH of 4.5 is 100 times more ,acid, than the soil with a pH of 6.5. Similarly, for every whole unit increase in pH above 7, there is a ten-fold increase in alkalinity. pH values are ,usually, reported to the nearest 1/10th of a whole unit on a soil test report (ie. 6.2, 7.0, 8.5).
